What didn’t the UV camera show sun damage?

Hi Dr. Iwin, My derm's assistance took a polarized picture of me. The picture showed that I did not have any sun damage. How it that possible when I have brown spots on my face? What's the best topicals to get rid of the brown spots? I know for sure I got these brown spots from staying out in the sun and not melasma.

You bring up a good point which is that lab tests, cameras, computer imaging, etc can all be in error sometimes or just not functioning well that day.  Since almost everyone has at least some sun damage by the age of 20, I suspect the camera wasn’t working properly.  Please see my article on to treat brown spots. You can also see the melasma article – just ignore the hormone section – everything else about prevention and treatment applies.  Dr. I

One of the best investments in your skin is your daily skincare. Why? Because you can prevent many problems with blotchy skin color, lack of glow, texture, some types of acne, and fine lines with good skincare products. You can also correct some of these problems with effective skincare products. Great skincare is often more expensive because quality ingredients are expensive. Some companies spend on research/development which benefits all of us and adds to the cost. Are they worth it? In general - yes!
